Biodegradable strain sensors able to undergo controlled degradation following implantation have recently received significant interest as novel approaches detect pathological tissue swelling or non-physiological stresses. In this study, the physicomechanical, electrochemical and active pressure sensing behavior of an electrically conductive biodegradable poly(glycerol sebacate urethane) (PGSU) ...

Carbon nanotubes (CNTs) have emerged as new class of nanomaterials that is receiving considerable interest because of their unique structure, mechanical, and electronic properties. One promising application of CNTs is to fabricate highly sensitive chemo/biosensors. For construction of these CNT-based sensors, the CNTs first have to be modified with some molecules specific to the interests. Gene...

This study explains the influence of secondary filler on the dispersion of carbon nanotube (CNT) reinforced high density polyethylene (HDPE) nanocomposites (CNT/HDPE). In order to understand the mixed-fillers system, Montmorillonite (MMT) was added to CNT/HDPE nanocomposites. It was followed by investigating their effect on the thermal, mechanical and morphological properties of the aforesaid n...

In the present study, using the powder metallurgy route, varying amount of nano-sized Y2O3 particulates and Nicoated carbon nanotubes (Ni-CNTs) were intentionally incorporated into the Sn-3.5Ag-0.7Cu solder to develop two nanocomposite solder systems. The samples were extruded and characterized in terms of their wettability, thermal, microstructural and tensile properties. Characterization resu...

The three-dimensional (3D) expanded graphite-carbon nanotube (EG-CNT) nanocomposite was prepared by in situ growing CNTs between graphite layers in thermally expanded graphite. The morphology and microstructure of the nanocomoposite were characterized by SEM, TEM, Raman and XRD analyses, respectively. The results show that intimately contacted EG-CNT interface has been formed within the multila...

although carbon nanotubes (cnt) have been employed as reinforcements in nanocomposites, presence of nano scale defects such as stone-wales and vacancy defects in carbon nanotubes (cnt) weakens the mechanical properties of these materials. in this paper the effects of defects in cnts on nanocomposite elastic behavior are investigated using molecular dynamics. stiffness matrices of cnt and nanoco...

in this paper, the effects of carbon nanotube (cnt) orientation and aggregation on the static behavior of functionally graded nanocomposite cylinders reinforced by cnts are investigated based on a mesh-free method. the used nanocomposites are made of the straight cnts that are embedded in an isotropic polymer as matrix. the straight cnts are oriented, randomly or aligned or local aggregated int...

We study the thermal buckling behavior of cylindrical shells reinforced with Functionally Graded (FG) wavy Carbon NanoTubes (CNTs), stiffened by stringers and rings, and subjected to a thermal loading. The equilibrium equations of the problem are built according to the Third-order Shear Deformation Theory (TSDT), whereas the stiffeners are modeled as Euler Bernoulli beams. Different types of FG...

The recent application of nanotechnology to structural materials is a promising way to produce new strong materials that exceed current limitations. Grain-size refinement is considered as one of the most effective strengthening methods of materials. At the same time, the addition of carbon nanotubes (CNTs) in a material is known to be more effective than conventional reinforcements. Here, CNT/C...
